Reduction of back switching by large damping ferromagnetic material
Tomohiro Taniguchi, Yohei Shiokawa, Tomoyuki Sasaki
Recent studies on magnetization dynamics induced by spin-orbit torque have revealed a weak dependence of the critical current for magnetization switching on the damping constant of…
Dependency of high-speed write properties on external magnetic field in spin-orbit torque in-plane magnetoresistance devices
Yohei Shiokawa, Eiji Komura, Yugo Ishitani +5
Spin-orbit torque (SOT) magnetoresistance (MR) devices have attracted attention for use in next-generation MR devices. The SOT devices are known to exhibit different write properti…
Finite-size scaling effect on Néel temperature of antiferromagnetic CrO-(0001) films in an exchange-coupled heterostructure
Satya Prakash Pati, Muftah Al-Mahdawi, Shujun Ye +3
The scaling of antiferromagnetic ordering temperature of corundum-type chromia films have been investigated. Néel temperature was determined from the effect of perpendicular…
Low-energy magnetoelectric control of domain states in exchange-coupled heterostructures
Muftah Al-Mahdawi, Satya Prakash Pati, Yohei Shiokawa +3
The electric manipulation of antiferromagnets has become an area of great interest recently for zero-stray-field spintronic devices, and for their rich spin dynamics. Generally, th…
Critical behavior of sputter-deposited magnetoelectric antiferromagnetic CrO films near Néel temperature
Muftah Al-Mahdawi, Yohei Shiokawa, Satya Prakash Pati +3
Chromium(III) oxide is a classical collinear antiferromagnet with a linear magnetoelectric effect. We are presenting the measurements of the magnetoelectric susceptibility of a…
Low-non-linearity spin-torque oscillations driven by ferromagnetic nanocontacts
Muftah Al-Mahdawi, Yusuke Toda, Yohei Shiokawa +1
Spin-torque oscillators are strong candidates as nano-scale microwave generators and detectors. However, because of large amplitude-phase coupling (non-linearity), phase noise is e…
Stoner gap in the superconducting ferromagnet UGe2
N. Aso, G. Motoyama, Y. Uwatoko +7
We report the temperature () dependence of ferromagnetic Bragg peak intensities and dc magnetization of the superconducting ferromagnet UGe2 under pressure (). We have found…
Anisotropic superconducting gap in transuranium superconductor PuRhGa: Ga NQR study on a single crystal
H. Sakai, Y. Tokunaga, T. Fujimoto +13
^{69,71}Ga NMR/NQR studies have been performed on a single crystal of the transuranium superconductor PuRhGa_{5} with Tc ~ 9 K. We have observed a ^{69}Ga NQR line at ~29.15 MHz, a…
